2 Claims.

This invention relates to ornamental stringers for slide operated closure fasteners. Closure fasteners of the type with which the present invention is concerned comprises in general a pair of stringers composed of fabric tapes provided at their inner, adjacent, longitudinally extending marginal edge portions with fastener elements which are engaged by a slider movable longitudinally of the stringer for opening and closing the fastener.

One object of the invention is to provide stringers which are attractive and pleasing in appearance whereby the closure fasteners comprising such stringers may be attached to garments and other articles in such manner as to constitute ornamental and decorative elements.

Another object of the invention is to provide ornamental stringers composed in part at least of metal or metal covered threads, such, for example, as tinsel threads or tinsel covered textile threads arranged in the stringers to impart a pleasing and ornamental appearance thereto without impairing the flexibility which is a desirable characteristic of such stringers.

Another object of the invention is generally to provide stringers of improved appearance.

The above objects ofthe invention and other objects which might hereinafter'appear will be fully understood from the following description considered with reference to the accompanying drawing.

In the drawing:

Fig. 1 is a view of a slide operated closure fastener provided with a pair of stringers embodying the present invention;

Fig. 2 is an enlarged sectional view on the line 2-2 of Fig. 1;

Fig. 3 is a greatly enlarged fragmentary view of one of the tinsel covered threads of which the stringers are at least partly composed;

Fig. 4 is a fragmentary view of a stringer, il' lustrating another form of the invention.

Referring now to the drawing in detail, the slide operated closure fastener I0 comprises, as here shown, a pair of stringers l2 having their inner, adjacent, longitudinally extending marginal portions each provided with companion cords l4 stitched or otherwise secured as usual to the opposite sides of the stringer providing means for the attachment of the usual metal or other interlocking or fastener elements it. A slider I8 is movable longitudinally of stringers l2 for engaging and disengaging elements It for closing and opening the fastener. Said stringers are as here shown, permanently Joined by an end connectlng member 20 but, if desired, may be provided instead with separable end connecting members of any suitable type, whereby the stringers may be completely separated.

Considering now the construction of stringers i2 in greater detail, the latter are seen to comprise outer salvage edge portions 20 extending longitudinally of the stringer tapes and com posed of textile warp threads 22 and textile weft threads 24 interwoven therewith. Cotton, silk or rayon are suitable for these threads. The inner marginal edge portion of the stringers which are provided with cord II have similar selvage edges and are similarly composed of said weft threads 24 and textile warp threads 22.

The intermediate portions 28 of the stringers are composed of said textile weft threads 24 and of ornamental warp threads 28. As clearly shown in Figs. 2 and 3, warp threads 28 each comprises in the form of the invention illustrated herein, a

textile thread 30 of cotton, silk or rayon about which is spirally wound a very narrow strip or thread 32 of very thin and flexible metal preferably tinsel which substantially covers the textile core or thread 30. Metal strips 32 are flat and pliable and in other respects possess the well known characteristics of tinsel strips. The tinsel may be of any desired color and may be provided in contrasting colors for obtaining a de sired surface appearance or design. Said ornamental threads 28 are arranged in close side by side relation, being interwoven with the weft thread or threads 24 which extend transversely of the stringers in close side by side relation, for forming together with threads 28 a firm and closely woven tape which, however, is advantageously highly flexible. The ornamental threads 8 28 are preferably somewhat thicker than weft threads 28 but yet, are very thin. For example,

in stringers which have been made in accordance a large multiplicity of closely arranged metallic surface portions visible on the other surface of the stringers. When said strips are as usual fiat, as hereinbefore indicated, said surfaces constitute facets which,.especial ly when the tinsel is lustrous provide numerous reflecting surfaces which contribute to the ornamental effect. The fastener elements l6 may be of the same or of a contrasting color with respect to the color of the ornamental threads 28, and by suitable combinations of colors, very attractive effects are obtained. Such effects may further be enhanced by the contrast between other portions of the stringers as, for example, the contrast in color between the corded portions and the intermediate portions 26. Similarly, outer edge portions 20 may contrast in appearance with said intermediate portions 26.

Numerous other combinations for obtaining stringers of different ornamental appearance may obviously be provided. Thus for example, in the form of the invention illustrated in Fig. 4, the intermediate portion of the stringer may comprise tinsel covered threads arranged in groups disposed in spaced relation laterally of the string with intervening portions of the stringer woven entirely from textile threads. In this connection,

referring to Fig. i, the stringer Eda has an intermediate portion 260. provided with groups of tinsel covered warp threads 28a which may be similar in all respects to threads 28 as illustrated in Figs. 2 and 3. The intervening portions 3d between the tinsel covered threads 28a may be composed of any textile threads arranged in the warp and interwoven with the textile weft threads such as the weft threads 20 illustrated in Fig. 2.

While I have shown and described the preferred embodiment of the present invention it is to be understood that the latter may be embodied otherwise than as here shown, for obviously the invention is susceptible of numerous forms. Therefore, I do not wish to be limited precisely to the construction herein shown or described, except as may be required by the scope of the appended claims.

What I claim and desire to secure by Letters Patent is:

1. An ornamental stringer for slide operated closure-fasteners comprising a tape provided with a longitudinally extending marginal edge portion adapted to have slider-operated fastener elements secured thereto and a longitudinally extending marginal edge portion for the securement of the stringer to the article to be provided therewith, said tape having, intermediate its inner and outer edge portions, a plurality of longitudinally extending threads covered with tinsel strips spirally wound thereon and visible on the outer surface of the stringer, said tinsel covered threads being disposed in close side by side relation in said intermediate part of the stringer and providing a multiplicity of light reflecting facets.

2. An ornamental slide-fastener stringer comprising a closely woven tape having at one side edge thereof a longitudinally extending marginal edge portion adapted to be secured to the article to be provided therewith and having at its other side edge a longitudinally extending marginal beaded edge portion adapted to be provided with slider-operated fastener elements, the longitudinally extending tape portion which is disposed between said marginal edge portions comprising weft threads disposed in close side by side relation and warp threads disposed in close side by side relation, some of said threads having very thin and flexible narrow strips of metal wound spirally thereon and visible on the outer surface of the stringer, said metal-covered threads extending in close side by side relation longitudinally of the stringer.
